  • Blade for a gas turbine
    Patent number: 8764395
    Abstract: The blade for a gas turbine includes a blade airfoil having a leading edge and a trailing edge and extending in the blade longitudinal direction up to a blade tip, and at the blade tip the blade airfoil merges into a shroud segment, wherein on the shroud segment a first rib, projecting upwards, is arranged in the flow direction, extending transversely to the flow direction, and upstream of the first rib, in the region of the leading edge of the blade airfoil, a winglet is formed on the shroud segment for guiding of the hot gas flow in this region. With such a blade, a longer service life is achieved by provision being made for direct cooling of the winglet.
    Type: Grant

  • Temperature probe
    Patent number: 5812588
    Abstract: In a temperature probe, in particular for use in the waste-gas diffusor of a gas turbine, a probe tube (1) projecting into the hot-gas region of the waste-gas diffusor is provided with an inner bore running in the direction of the tube axis of the probe tube (1). At the same time, the probe tube (1) is provided over its length with a number of throughflow ducts running transversely relative to the tube axis and in which are located a number of thermocouples (22), the connecting points (23) of which are arranged in the throughflow ducts. The thermocouples (22) are connected to a compensating line (13) in a terminal box (14). Each thermocouple (22) is arranged in a solely heat-movably guided manner in a protective tube (18) which is fixed relative to the inner bore of the probe tube (1).
